Xorg Prime: enable Prime for offloading from Radeon to Intel GPUs.

xrandr --setprovideroutputsource Intel "HAWAII @ pci:0000:01:00.0"
xrandr --auto

The names are listed on xrandr --listproviders.
The first provider is the one that will output the image to the monitor (in this case, the integrated Intel GPU). The second parameter is the source of the image, that is, the GPU that will do the actual rendering. In this case a Radeon 290x (Hawaii chip) will render the Xorg desktop.

The second command, xrandr --auto will set up the multi monitor configuration.
